Looks good, man. COBs are good lighting, though, not supplemental lighting. The post I was responding to, by you (right?), said that COB were good supplemental lighting. I meant to assert they are ready for prime-time, based on 1.4gpw from some random noob you referenced from the internets doing a 600W@ COB grow.
You are deep within The Narcissism of Small Differences at this point, but you can grow, I'm not hatin' on that.
I think all lights are valid, and COB are among the best, and soon (couple of years, no more than 5) will be the industry standard. That's my stance, and I'd like to see it refuted with data, but it won't be.
P.S. You're alright with me, sorry for fucking with you, unlike some I've already ignored up in here.
